Equivalent Of Ezscript's "Sleeprandom(A,B)" For Python ?

Hi,
I used to use a lot SleepRandom(a,b) in my EZ-scripts to simulate random behaviors.
I don't find the equivalent for Python scripting.

Outside of ARC, I use the "random" module (random module), but it does not seem to be present in ARC

Code:

import random
returns "No module named random".

Is there a way to achieve the same thing than SleepRandom with Python scripting in ARC, or is there a way to import the python random module?
Thanks

Weird that it's _random.... hmm! Random:D

Code:


import _random

random = _random.Random()

print random.random()

Thanks @DJ !
I could have searching for it forever....:D

_random works too but asfaik in Python 2 std library random exists.

@DJ:
You can make it work the same way. You will need to add an additional nuget package to your ARC project:

Regarding the _random:

Quote:

It is common practice to use a leading underscore for modules implemented in C.
The other reason is too avoid duplicated import names for the same functionality: _module1 can be called from CPython (C) and a module1 (py) wrapper can coexist and internally calls _module1.

Quote:

You will find this for several modules of the standard library.

Typically, you should use module1 and not _module1.

That’s good to know! Thanks ptp. I seem to be learning python as we go as well:)

It seems that I cannot use any other attribute than .Random

These following attributes, part of the random module, don't work:

>>> random.uniform(1, 10) # Random float x, 1.0 <= x < 10.0
>>> random.randint(1, 10) # Integer from 1 to 10, endpoints included
>>> random.randrange(0, 101, 2) # Even integer from 0 to 100
>>> random.choice('abcdefghij') # Choose a random element

For example, I tried random.Randint , _random.randint , _random.Randint. Each of them returns

Code:

'module' object has no attribute 'randint'


Is it me who is missing something... Again ?

I added this to the next update. Stay tuned

I tested rapidly the new beta version before going to work and the "random" module works great, with all the attributes (and without the "underscore" :D)
Thanks @DJ
